The 1.5KE43AE3/TR13 is listed as Obsolete by Microsemi, meaning the manufacturer no longer produces it. The 36.8V reverse standoff voltage means it starts conducting above that level, protecting downstream circuitry from transients.
Housed in a DO-201AA (DO-27) axial-lead through-hole package, with the supplier device package designated CASE-1.
